long bolts in crankcase
K2-K6:
Reminds me of this

But on a more serious note for the OP, generally wise to go with and insert/repair on these engines to preserve original bolts and thread sizes.
It shouldn't be difficult to complete either.
Brett72:
I have used helicoils before and they are obviously the cheaper option but will they withstand the bolts being torqued into them?
Nurse Julie:
Which one is it exactly that has stripped?

The thread in the top crankcase for bolt no.2 in the picture at the start of this thread
K2-K6:
Properly installed the helicoils are fine for torque rating.
Some high use structures in aluminium use them routinely as the threads are more durable to multiple use, they don't get anything like that in this application as so infrequently removed.
